New study suggests more and longer atmospheric stagnation events due to global warming
Study shows how early Earth kept warm enough to support life
Solving the "faint young sun paradox"—explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today—may not be ...
Low-sodium diet key to a stellar old age, astronomers find
(Phys.org) —Astronomers expect that stars like the Sun will blow off much of their atmospheres into space near the ends of their lives. But new observations of a huge star cluster made using ESO's Very ...
New rhythm for El Nino discovered
El Niño wreaks havoc across the globe, shifting weather patterns that spawn droughts in some regions and floods in others. The impacts of this tropical Pacific climate phenomenon are well known and documented.
Cities affect temperatures for thousands of miles
Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. In a new study that shows the extent to which human activities are influencing the atmosphere, scientists ...
Tropical Indo-Pacific climate shifts to a more El Nino-like state, research finds
Climate models predict a slowdown of the Walker circulation with global warming. Atmospheric models, however, have failed to reproduce the slowdown already observed over the last 60 years, casting doubt on ...
Study: Arctic sea ice decline may be driving snowy winters seen in recent years
A new study led by the Georgia Institute of Technology provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study's ...
In distance space, a water world: Hubble reveals a new class of extrasolar planet
(PhysOrg.com) -- An international team of astronomers led by Zachory Berta of the Harvard-Smithsonian Center for Astrophysics (CfA) made the observations of the planet GJ 1214b.
In nitrogenase - enzyme critical for life, X-ray emission cracks mystery atom
Like a shadowy character just hidden from view, a mystery atom in the middle of a complex enzyme called nitrogenase had long hindered scientists' ability to study the enzyme fully.
What caused a giant arrow-shaped cloud on Saturn's moon Titan?
(PhysOrg.com) -- Why does Titan, Saturn's largest moon, have what looks like an enormous white arrow about the size of Texas on its surface?
Early Earth haze likely provided ultraviolet shield for planet
A new study shows a thick organic haze that enshrouded early Earth several billion years ago may have been similar to the haze now hovering above Saturn's largest moon, Titan, and would have protected primordial ...
Carbon Atmosphere Discovered on Neutron Star
(PhysOrg.com) -- Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year ...
Global warming: Our best guess is likely wrong
No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study this week suggests scientists' best predictions about global warming might be incorrect.
Study finds that soil carbon may not be as stable as previously thought
Increased plant growth caused by rising atmospheric carbon dioxide is associated with higher rates of carbon dioxide release from soil. If rising carbon dioxide enhances soil carbon storage at all, the effect ...
